Let me see if I've got this straight-
It's no good to trust any particular brand of drive because drive failure is just a part of life and the best solution is to be prepared for it.
The best preparation is some sort of backup plan- either synced mirrors or RAID5 boxes.
Data storage has two basic 'constraints'- getting enough space and making it reliable/robust.
I'm trying to get an outline in my head of the specific 'robustness' strategy involved, so pardon my mental gear grinding. Please feel free to clarify or correct me (it's a forum, and that's the whole point).
Data is best to store on RAID - either internal (card) or external (NAS). I suspect that internal has faster access and is less obtrusive- what other advantages does it have?
OS and
programs are best placed on individual drives (and/or separate partitions of an internal RAID).
OS and
programs shouldn't (or can't?) be run from RAID and therefore should be backed up (or at least the personal configuration files) to some safe data storage configuration (again, either RAID or a mirrored drive).
If not backed up,
OS and
programs could just be rebuilt from the original source (which is just data). Hmm- if your OS is corrupt then you won't have access to the source data except via CD, so RAID storage of the source seems silly (but that's just the sort of thing I'm trying to figure out here, so go with me on this).
It seems from other threads that RAID card selection is deathly important, although (from this thread) drive brand is not.
I don't see the value in assembling arrays of small drives. Too much hassle for too little gain?
...and then there's the concept of data protection from threats
external to the computer- ie: fire, flood, etc.
For this, some syncing of data to a remote RAID/server seems the proper way to go. Sort of out of the range of my concerns on this day, but probably an important consideration for the next few years.
My usage is simply personal/home use- I'm not thinking in terms of business operation, just music/photos/entertainment/personal records/etc storage and manipulation.
I'm running an old HP Pavilion with two large (40GB+) drives in it (no mirror) and a homebrew NAS (Debian/RAID5).
I'm sort of lazy about the whole back-up thing, so I haven't tried many things to ensure I can recover the HP (stuff on the Debian box should survive a drive death). I tried to set up an automatic backup via the tools Bill Gates provided me in the WinME on the HP, but that software only wants to store the recovery data on a 'removable' device, so I couldn't create the backup on the second drive or the NAS. Could I mount a directory on the NAS as such a device?
Or would that defeat the whole purpose? (ie: recovering the HP would then require the NAS to be reinstated as such a device before the HP could be rebuilt)
Then there's the technology-timeline to consider... new drives and storage solutions might make some of these concerns (above) moot. Like the
Hitachi vertical bit drives. No worries with storage space, there!
If data storage solutions of the near future solve issues of space and reliability, then it doesn't seem like investing
loadsof time, effort, and money into backup solutions for personal use is warranted. Obviously,
some effort/time/money should be invested, but it's just a balance thing, I guess.
Hmm- lots to think about for my backup/recovery-newbie brain.
If you've stuck with me this far, I thank you for your time.
If you're inclined to respond, I'm interested and appreciate hearing your thoughts.
I should just dump $200 on an external USB drive to make my backups to, eh?
